Alcohol may have played a role in an early morning two-vehicle crash where a Shelby Township man was killed and another man was seriously injured, Shelby Township police said Sunday.

Investigators are still trying to piece together the circumstances of the accident.

Officers were called to 23 Mile Road between Ryan and Shelby roads about 3:45 a.m. A 60-year-old Shelby Township man was found unconscious in a 2005 Chrysler 300. A 21-year-old Troy man was found unconscious in a 1999 Mercury SUV. Both had to be removed from their cars with rescue tools.

The 60-year-old was pronounced dead at Troy Beaumont Hospital. The 21-year-old is being treated for serious injuries.

Officials are not releasing the name of the deceased pending next-of-kin notification.

Anyone with information is asked to contact the police at 586-731-2121.
